Single-valued periods of meromorphic modular forms and a motivic interpretation of the Gross-Zagier conjecture

Francis Brown, Tiago J. Fonseca

A well-known conjecture of Gross and Zagier states that the values of the higher automorphic Green's function at pairs of points with complex multiplication in the upper half-plane…

The wheel classes in the locally finite homology of $GL_{n} (Z)$ , canonical integrals and zeta values

Francis Brown, Oliver Schnetz

We compute the canonical integrals associated to wheel graphs, and prove that they are proportional to odd zeta values. From this we deduce that wheel classes define explicit non-z…
